Salt stress can affect various physiological processes in plants, ultimately hindering their growth and development. Melatonin (MT) effectively resist multiple abiotic stresses, improving plant resistance. To analyze the mechanism of exogenous MT to enhance salt tolerance red clover, we conducted a comprehensive study examine influence on parameters, including seed germination indices, seedling morphological traits, photosynthetic indicators, using four distinct clover varieties (H1, H2, H3, H4). This investigation was performed under conditions with differing pH values, specifically utilizing NaCl, Na2SO4, NaHCO3, Na2CO3 as stressors. The results showed that solution immersion significantly improved indicators seeds stress. foliar spraying 50 μM 25 increased SOD activity (21–127%), POD activity, soluble sugar content, proline content (22–117%), chlorophyll (2–66%), net rate. It reduced MDA (14–55%) intercellular CO2 concentration seedlings Gray correlation analysis Mantel test further verified is key factor enhancing stress; most significant improvement observed for NaHCO3 demonstrated improve through variety mechanisms, an increase antioxidant enzyme osmoregulation ability, cell membrane stability. Additionally, it improves efficiency architecture, promoting energy production, growth, optimal resource allocation. These mechanisms function synergistically, enabling sustain normal development

Melatonin is a hormone-like substance that serves as secondary metabolite associated with variety of physiological, hormonal, and natural processes at the cell, tissue, organ levels. It acts plant biostimulant increase tolerance against abiotic stresses like ssalinity, drought, heat, cold heavy metals. in plants, also called phytomelatonin, participating cellular mechanisms ameliorates oxidative toxicity, hence helps to stand stress conditions. These exclusive properties strengthen defense capacity by stimulating detoxification reactive oxygen species (ROS), promoting physiological attributes, activation stress-responsive genes ameliorate toxicity caused stress. As key molecule, it exhibits several important molecular interactions nitric oxide (NO), calcium (Ca2+), hydrogen peroxide (H2O2) sulfide (H2S). In this review article, we discuss salient role melatonin morphological adaptation well its involvement mitigation. Besides, under stress, interaction NO, Ca2+, H2O2, H2S has been demonstrated. This study will provide reference for elucidating regulatory mechanism influencing resistance plants.

In order to analyze the physiological regulation mechanisms associated with exogenous melatonin on rice blast, this study treated seedlings different concentrations of (0, 20, 100, and 500 µmol/L) in investigate growth characteristics, root morphology, superoxide dismutase (SOD) activity, peroxidase (POD) catalase (CAT) malondialdehyde (MDA) content, hydrogen peroxide (H2O2) soluble protein content seedlings. The results indicated that 100 µmol/L exhibited a significant effect, improving antioxidant capacity under blast fungus infection. disease resistance level against significantly decreased by 31.58% when compared 0 treatment, while plant height, stem base width, leaf area, total length, aboveground dry weight, fresh underground weight increased 8.72% 91.38%. Treatment activities respective increases 94.99% 31.14%. Simultaneously, contents decreased, reaching 18.65% 38.87%, respectively. gray relational grade analysis exhibit highest grades concentration and, so, can be used evaluate effect severity Furthermore, membership function revealed treatment had value, indicating improvement disease. conclusion, enhances through promoting their strengthening defenses. This provides new insights into tolerance

Melatonin is a potent antioxidant that can prevent plant damage caused by adverse stresses. It remains unclear whether exogenous melatonin mitigate the effects of salt stress on seed germination and seedling growth sorghum (Sorghum bicolor (L.) Moench). The aim this study was to decipher protective mechanisms (100 μmol/L) seedlings under NaCl-induced (120 mmol/L). Plant morphological, photosynthetic, physiological characteristics were analyzed at different timepoints after sowing. Results showed inhibited germination, growth, biomass accumulation reducing photosynthetic pigment contents, efficiency, root vigor, mineral uptake. In contrast, priming with enhanced biosynthesis, K+ content stress. application additionally activities enzymes (superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase) increased levels non-enzymatic antioxidants (reduced glutathione, ascorbic acid) in leaves. These changes accompanied increase leaf contents soluble sugars, proteins, proline, as well decrease hydrogen peroxide accumulation, malondialdehyde content, electrolyte leakage. Our findings indicate alleviate stress-induced through multifaceted mechanisms, such improving performance facilitating ion homeostasis osmoregulation, promoting defense reactive oxygen species scavenging.
